摘要： Embodiments of the present invention help to suppress the effects of thermal fluctuation in a thermally assisted magnetic field recording, and improve recording density. According to one embodiment, a recording area of a magnetic disk is heated and the full width at half maximum of an optical power distribution of a near field light generator is controlled to be 100 nm or less. Thereby, the cooling time of the magnetic disk is made 2 nm or less and the effects of thermal fluctuation are suppressed. Moreover, although an incomplete area of the magnetization reversal at the rear end of the magnetic domain is created with rapid cooling, by creating an overshoot at the rising end of the magnetic field waveform of the magnetic recording head, the incomplete area of the magnetization reversal can be overwritten, which is created at the rear end of the magnetic domain previously recorded by the overshoot magnetic field. Therefore, the expansion of the magnetic transition width can be suppressed, resulting in the recording density being improved.

摘要： A method of flip-chip mounting can reliably and stably mount a semiconductor chip to a mounting substrate while avoiding problems such as damage to the semiconductor chip due to a difference in thermal expansion coefficients between the semiconductor chip and the mounting substrate. The method of flip-chip mounting a semiconductor chip supports a mounting substrate on a stage in a state where a resin material has been supplied onto a chip mounting surface of the mounting substrate and presses the semiconductor chip toward the mounting substrate using a pressure/heat applying head to bond the semiconductor chip to the mounting substrate and thermally harden the resin material. A concave part is provided in a support surface of the stage that supports the semiconductor chip, and the semiconductor chip is bonded to the mounting substrate by pressing the semiconductor chip toward the mounting substrate using the pressure/heat applying head in a state where the mounting substrate is bent toward the concave part.

摘要： A method and instrument for measuring, with a high spatial resolution, a magnetic or electric field that varies repeatedly at high speed. An electron beam is deflected by passage through a magnetic or electric field to be measured and is allowed to pass through a deflection electrode to thereby be deflected in a direction perpendicular to the magnetic or electric field to be measured. A track of the deflected electron beam is detected by a two-dimensional sensor, and a waveform or pattern is displayed wherein a time base and an axis of the magnetic field to be measured are orthogonal to each other.

摘要： When an R/C helicopter of a single rotor type is configured to have a small size and light weight to be used indoors, a flying operation thereof can be stabilized and operability can be improved.A center hub that supports a rotor head to a mainmast is divided into an upper center hub and a lower center hub, and the upper and the lower center hubs are fixed around the shaft of the mainmast with a predetermined angle. A phase angle of a main rotor as an output with respect to an operation input from a swash plate becomes an acute angle, and the main rotor and a stabilizer are mounted to rotate with a phase difference of the acute angle.
